As stated in the title, they get the following error:
############################################################################################ FATAL ERROR in action number 1 of Other Event: Game Start for object obj_music_controller: ds_map_find_value argument 1 incorrect type (undefined) expecting a Number (YYGI32) at gml_Script_scr_checkLastLoggedInJson ############################################################################################ -------------------------------------------------------------------------------------------- stack frame is gml_Script_scr_checkLastLoggedInJson (line -1) gml_Object_obj_music_controller_Other_2
The function ds_map_find_value() is not being called in the script scr_checkLastLoggedInJson(). (Even if it was, how could it be happening at line -1?)
Nor is it called in the Game Start event of the obj_music_controller object. I also checked every use of ds_map_find_value() in the entire game and they are all fine.
Furthermore, this is only happening with 1 person. And they have tried uninstalling it and re-downloading. Even after i uploaded a new version of the game, this still happened to them and only them.
